Ollama

Ollama is currently the most popular tool for running local large language models, offering a Docker-like experience — users can download and run hundreds of open-source models such as Llama, Mistral, DeepSeek, and Qwen with just one command. It provides a REST API compatible with OpenAI, enabling seamless integration with various AI applications. The platform supports GPU acceleration, parallel processing of multiple models, and custom Modelfile configurations. The community has contributed tens of thousands of integration solutions for use cases ranging from chatting to programming and RAG. After releasing a native desktop application in 2025, it became easier even for non-technical users to get started. Whether developers need to quickly set up API services or individual users want to experience large language models locally, Ollama remains the most hassle-free choice.
